# [−][src]Crate as_slice

`AsSlice` and `AsMutSlice` traits

These traits are somewhat similar to the `AsRef` and `AsMut` except that they are NOT polymorphic (no input type parameter) and their methods always return slices (`[T]`).

The main use case of these traits is writing generic code that accepts (fixed size) buffers. For example, a bound `T: StableDeref + AsMutSlice<Element = u8> + 'static` will accepts types like `&'static mut [u8]`, `&'static mut [u8; 128]` and `&'static mut GenericArray<u8, U1024>` -- all of them are appropriate for DMA transfers.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
